IMPLEMENT EoitsHEARINe SHEEP.

Specification of Letters Patent No. 12,760, dated April 24:, 1855.

Be it known thatl, PALMER LANCASTER, of Burr Oak, in the county of St. Joseph and State of Michigan, have invented anew and Improved Implement for Shearing Sheep; and I do hereby declare that the i following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a longitudinal section of my improvement. Fig. 2,1is a plan or top view of ditto. Fig. 3, is a transverse section of it (w) i Fig. 2', showing the plane of sect1on. y y V "Similar letters of reference indicate corresponding parasin the-several figures.

The nature of my invention, consists in thepeculiar constructionwof the implement as will be hereafter shown and described,

whereby the operation of sheep shearing in a perfect and expeditious manner. 1 r

To enable others skilled in the art to make and use my invention, Iwill proceed to describe its construction and'operation.

A, represent two, metallic platessecureda short distance apart by bolts o-r rods (0i) shownin Figs. 1 and 2. These plates may be of rectangular or other proper form. r t

t on the upper surface'ilof the upper plate A, there is asliding frame B'whichworks between suitable guides (12) I The sliding frame is provided with anupright handle I]. Ateach side ofthe'frame B, there is attached a rack D, D, the rack D. being somewhat higher or projecting further up from the frame B, than the rack D, as clearly shown in Fig)? r E, represents a vertical shaft which works between thetwoplates A, A. The upper end a of this shaftextendsa short distance above a the upper plate A, and has two pinions F,

F, placed looselyupon it, one pinion being directly over theother. There are also on r nently attachedtothe shaft, the ratchet (a) ,being above the pinion F, and the ratchet (0') below the pinion F. To each of the pinions F, F, there is secured a pawl (d) the ends of which are kept against the teeth ofthe ratchetby springs (e The rack D, gears into the upper pinion F, and the rack D, on the opposite side of the frame B gears into the pinion F.

On the shaft E and between the two plates A, A, there is attached a spur wheel G, which gears into a pinion H, having a crank pulley I above it on the same axis or shaft. To the crank pulley there is attached a connecting rod J, the outer end of which is secured to an arm K of a series of cutters (f) which work on a pivot (g), the cutters (f) being of saw tooth formand attached to a common plate L, through which the pivot (g) passes, see Figs. 1 and 2.

The cutters (f) are directly over a series of stationary cutters (h) which are formed at the end of a plate M attached to the front end of the lower plate A. The cutters (h) are of thesame form as the cutters (fi) but 7 are inclined a little upward as shown in Fig. 1. The cutters (f) are very slightly inclined,

To theback end of the lower plate A there is attached a handle N having a bow O,

at its end. The bow O is placed under the shoulder of the operator, and may if necessary be secured thereto by straps. The implement is placedupon the body of the sheep and the handle G is grasped by the right hand and moved back and forth, and a continuous rotary motion is given the spur wheel G in consequence of the pinions F, F onlybeing connected to the shaft E when turned in) one direction, viz, .from left to right. This is efiected by the pawls (d) (0?); As the spur wheel G gears into the pinion H a vibratory motion is given the cutters ,(f) by means of the connecting rod K, and the cutters (f) work over the cutters (h) similar to the blades of shears, and

will cut the wool from the animal in a perfect and expeditious manner, the implement of course as it cuts being moved over the'body of the animal.

The advantage of this invention besides the rapidity, with which it operates is, that the implement will not mince or cut the wool twice, nor cut the animal as is often done with the ordinary sheep shears.

of stationary cutters (h), the cutters of the spur Wheel G, the above parts being (f) having a vibratory movement given arranged as shown and operating in the them by means of the reciprocating frame manner and for the purpose as set forth.
